Put the socket splicing fields into a seperate struct sosplice that
gets only allocated when needed. This way struct socket shrinks
from 472 to 392 bytes on amd64. When splicing gets active, another
88 bytes are allocated for struct sosplice.
OK dlg@
but sosplice(9) still documents the old unexisting structures, so let's
change it to mention the new struct sosplice.
The following sounds a bit quirky; any better way to put it?
[...] by setting these additional fields in the struct
sosplice *so_sp field in struct socket:
Note how I also changed the mdoc macro `Fa' (function argument) to `Va'
(variable name) as that seems more appropiate. Ingo?
Feedback? OK?
